Re: Panasonic tx-55650b

i bought a new m/b and a new t con. with the new m/b no backlight and no 12v on the test point between lvds to tcon so i am guessing its no good. with old m/b and new t con no change just backlight. i took off one ribbon to panel and the other side just has vertical lines. when you switch between sources on tv the backlight changes brightness. I have a feeling panel is bad but not sure how to test to find out for sure.

Hi
I have a panasonic tx-55as650b lcd tv which all of a sudden lost its picture, but the backlight was still on. All p/s voltages are good and there is voltage on the output of the t con board. I bought a replacement motherboard and with this one in place there is no backlight the SRV-VLED remains at 24 volts (original m/b switches it to 46v) there is no voltage at srv 12v for t con and the green power led blinks rapidly before going solid. when i remove the ribbon to the panel on one side the other side has vertical lines of various colours which disappear when the ribbon is plugged in....
